How to Convert Terahertz to Nanometers

Wavelength and frequency are inversely related through the speed of light. The formula is: λ = c / f, where λ is the wavelength, c = 299,792,458 m/s (speed of light in vacuum), and f is the frequency.

Conversion Steps

  • The formula is: Wavelength = Speed of Light / Frequency
  • For example, to convert 220 THz to nm:
  1. Convert to hertz: 220 THz = 220 × 1.0e+12 = 2.2e+14 Hz
  2. Apply formula: λ = 299,792,458 / 2.2e+14 Hz = 1.36269e-6 meters
  3. Convert to nanometers: 1.36269e-6 m / 1.0e-9 = 6.59543e+7 nm

Reverse Conversion

To convert nanometers back to terahertz, use f = c / λ:

  • 6.59543e+7 nm → f = 299,792,458 / 1.36269e-6 m = 2.2e+14 Hz → 220 THz
